Hello - I pulled two hurricane reports (api/.../currenthurricane) two hours apart. Although the timestamp (Current.TimeGMT.epoch, et al.) didn't change, several of the report's values changed - specifically, the forecasts for category and windspeed changed between the two reports.

Please see attached screenshots.

Is there not an identifier within the response/report itself that indicates when the report was last updated? I thought that would be the purpose of the Current.Time/TimeGMT fields. I'd be kind of surprised if there weren't some kind of timestamp and/or version number for a storm as its reports (both current and forecast) are updated, so I presume I'm missing something.

Also, how often does Wunderground update its 'currenthurricane' information? I want to poll frequently enough but not too frequently. :)
